Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning

resemble the flu, with headaches, dizziness, and/or nausea. If you have these signs,

the heater may not be working properly. Get fresh air at once! Have heater serviced.

Some people are more affected by carbon monoxide than others. These include

pregnant women, people with heart or lung disease or anemia, those under the

influence of alcohol, and those at high altitudes.

Propane Gas: Propane gas is odorless. An odor-making agent is added to propane

gas. The odor helps you detect a propane gas leak. However, the odor added to

propane gas can fade. Propane gas may be present even though no odor exists.

Make certain you read and understand all Warnings. Keep this manual for reference.

It is your guide to safe and proper operation of this heater.

FRESH AIR

FOR

COMBUSTION

AND

VENTILATION

WARNING ICON G 001

WARNING

This heater must have fresh air for proper operation. If not, poor

fuel combustion could result. Read the following instructions to

insure proper fresh air for this and other fuel-burning appliances

in your home.

Today’s homes are built more energy efficient than ever. New materials, increased

insulation, and new construction methods help reduce heat loss in homes. Home

owners weather strip and caulk around windows and doors to keep the cold air out

and the warm air in. During heating months, home owners want their homes as

airtight as possible.

While it is good to make your home energy efficient, your home needs to breathe.

Fresh air must enter your home. All fuel-burning appliances need fresh air for

proper combustion and ventilation.

Exhaust fans, fireplaces, clothes dryers, and fuel burning appliances draw air from

the house to operate. You must provide adequate fresh air for these appliances.

This will insure proper venting of vented fuel-burning appliances.

PRODUCING ADEQUATE VENTILATION

All spaces in homes fall into one of the three following ventilation classifications:

1. Unusually Tight Contruction; 2. Unconfined Space; 3. Confined Space.

The information on pages 5 through 8 will help you classify your space and provide

adequate ventilation.

Unusually Tight Construction

The air that leaks around doors and windows may provide enough fresh air for

combustion and ventilation. However, in buildings of unusually tight construction,

you must provide additional fresh air.

Unusually tight construction is defined as construction where:

a. walls and ceilings exposed to the outside atmosphere have a continu-

ous water vapor retarder with a rating of one perm or less with open-

ings gasketed or sealed

and

b. weather stripping has been added on openable windows and doors

and

c. caulking or sealants are applied to areas such as joints around window

and door frames, between sole plates and floors, between wall-ceiling

joints, between wall panels, at penetrations for plumbing, electrical, and

gas lines, and at other openings.

If your home meets all of the three criteria above, you must provide addi-

tional fresh air. See

Ventilation Air From Outdoors

, page 8

If your home does not meet all of the three criteria above, continue reading.

Unconfined Space

An unconfined space has a minimum air volume of 50 cubic feet for each 1000

BTU/Hr input rating of all appliances in the space (cubic feet equals length x

width x height of space). Include adjoining rooms only if there are doorless

passageways or ventilation grills between the rooms.

Confined Space

A confined space has an air volume of less than 50 cubic feet for each 1000

BTU/Hr input rating of all appliances in the space (cubic feet equals length x

width x height of space). Include adjoining rooms only if there are doorless

passageways or ventilation grills between the rooms.

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION

Determining if You Have a Confined or Unconfined Space

Use this worksheet to determine if you have a confined or unconfined space.

Space: Includes the room in which you will install heater plus any adjoining rooms with

doorless passageways or ventilation grills between the rooms.

1. Determine the volume of the space (length x width x height).

Length x Width x Height = ___________________ cu. ft. (volume of space)

Example:

Space size 18 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) =

2304 cu. ft. (volume of space)

If additional ventilation to adjoining room is supplied with grills or openings, add the

volume of these rooms to the total volume of the space.

2. Divide the space volume by 50 cubic feet to determine the maximum BTU/Hr the space

can support.

____________ (volume of space) ÷ 50 cu. ft. = (Maximum BTU/Hr

the space can support)

Example:

2304 cu. ft. (volume of space) ÷ 50 cu. ft. = 46.1 or 46,100 (maximum

BTU/Hr the space can support)

3. Add the BTU/Hr of all fuel burning appliances in the space.

Vent-free heater ___________________ BTU/Hr

Gas water heater* ___________________ BTU/Hr

Gas furnace ___________________ BTU/Hr

Vented gas heater ___________________ BTU/Hr

Gas fireplace logs ___________________ BTU/Hr

Other gas appliances* + ___________________ BTU/Hr

Total = ___________________ BTU/Hr

Example:

Gas water heater 40,000 BTU/Hr

Vent-free heater + 10,000 BTU/Hr

Total = 50,000 BTU/Hr

* Do not include direct-vent gas appliances. Direct-vent draws combustion air from the

outdoors and vents to the outdoors.

4. Compare the maximum BTU/Hr the space can support with the actual amount of BTU/

Hr used.

_________________ BTU/Hr (maximum the space can support)

_________________ BTU/Hr (actual amount of BTU/Hr used)

Example:

46,100 BTU/Hr (maximum the space can support)

50,000 BTU/Hr (actual amount of BTU/Hr used)

The space in the above example is a confined space because the actual BTU/Hr used is

more than the maximum BTU/Hr the space can support. You must provide additional fresh

air. Your options are as follows:

A. Rework worksheet, adding the space of an adjoining room. If the extra space provides

an unconfined space, remove door to adjoining room or add ventilation grills between

rooms. See Ventilation Air From Inside Building, page 7.

B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 8.

C. Install a lower BTU/Hr heater, if lower BTU/Hr size makes room unconfined.

If the actual BTU/Hr used is less than the maximum BTU/Hr the space can support, the

space is an unconfined space. You will need no additional fresh air ventilation.

CONNECTING

TO GAS

SUPPLY

NOTICE

A qualified service person must connect heater to gas supply.

Follow all local codes.

The installer must supply an external regulator. The external regulator will reduce

incoming gas pressure. You must reduce incoming gas pressure between 11 and 14

inches of water. If you do not reduce incoming gas pressure, heater regulator

damage could occur. Install external regulator with the vent pointing down as

shown in Figure 12. Pointing the vent down protects it from freezing rain or sleet.

Install sediment trap in supply line as shown in Figure 13, page 14. Locate sediment

trap where it is within reach for cleaning. Locate sediment trap where trapped

matter is not likely to freeze. A sediment trap traps moisture and contaminants. This

keeps them from going into heater controls. If sediment trap is not installed or is

installed wrong, heater may not run properly.

Installation must include a manual shutoff valve, ground joint union, and plugged

1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must

be upstream from heater (see Figure 13, page 14).

Apply pipe joint sealant lightly to male threads. This will prevent excess sealant

from going into pipe. Excess sealant in pipe could result in clogged heater valves.
